When two boats share the same hull type — in this case both the World Cat 320EC Express Cabin 2008 and the World Cat 330TE Tournament Edition 2012 are catamaran designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — World Cat 320EC Express Cabin 2008 at 32,0 ft versus World Cat 330TE Tournament Edition 2012 at 34,0 ft. At 109 lbs and 104 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 700 hp, the World Cat 320EC Express Cabin 2008 has a 100-hp advantage over the World Cat 330TE Tournament Edition 2012's 600-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the World Cat 320EC Express Cabin 2008 carries 26 gallons versus 3 gallons in the World Cat 330TE Tournament Edition 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The World Cat 330TE Tournament Edition 2012 is rated for 10 passengers, while the World Cat 320EC Express Cabin 2008 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the World Cat 330TE Tournament Edition 2012 could be the deciding factor.
